SAN ANTONIO — For a moment, it looked like UTSA was headed for another long afternoon.
Then the Roadrunners' offense came alive.
UTSA erased a 14-point deficit with five consecutive touchdowns and held off Colorado State for a wild 59-45 victory Saturday at the Alamodome, bouncing back from its loss at Texas with one of the most explosive offensive performances in program history.
A week after scoring just six points in Austin, the Roadrunners put up 59.
And they needed nearly all of them.
Colorado State stunned UTSA from the opening kick. Mel Brown returned it 94 yards for a touchdown, and after the Roadrunners came up empty on their first possession, Rams quarterback K'saan Farrar connected with Terrence Smith Jr. for a 74-yard score.
Less than two minutes into the game, UTSA was down 14-0.
Whatever momentum the Roadrunners hoped to establish after the loss to Texas appeared to be disappearing almost immediately.
Instead, UTSA answered.
Brandon High Jr. finished a 12-play, 75-yard drive with a 16-yard touchdown run to cut the deficit in half. After the defense forced a quick Colorado State punt, Will Henderson III scored from 13 yards out to tie the game.
Then UTSA took control.
Owen McCown connected with David Amador II for a 27-yard touchdown late in the first quarter, giving the Roadrunners their first lead of the afternoon and completing a 21-point response to Colorado State's opening barrage.
McCown wasn't done.
He found DJ Allen Jr. for a 58-yard touchdown early in the second quarter before A'Marion Peterson added a five-yard rushing score.
In a little more than a quarter, UTSA had transformed a 14-0 deficit into a 35-14 advantage.
Colorado State finally stopped the run with a touchdown before halftime, sending UTSA to the locker room with a 35-21 lead.
But if the first half belonged to the Roadrunners, the second became a test of whether they could survive the shootout.
The Rams scored on their opening possession of the third quarter to pull within seven.
UTSA needed only one play to respond.
Mekhi Anderson took the ensuing kickoff 100 yards for a touchdown, delivering one of the biggest plays of the afternoon and restoring a two-possession advantage.
Colorado State kept coming.
The Rams eventually cut UTSA's lead to 49-42 in the fourth quarter, putting the pressure back on an offense that had spent much of the afternoon answering every challenge.
McCown answered again.
The UTSA quarterback found Anderson for a 14-yard touchdown with 5:43 remaining, giving the Roadrunners some much-needed breathing room at 56-42.
Colorado State added a field goal, but Peterson's 47-yard run on UTSA's next possession helped put the game away. A late field goal produced the final 59-45 margin.
By the time it was over, the two teams had combined for 104 points and 1,042 yards of offense.
UTSA accounted for 542 of those yards, producing 303 through the air and another 239 on the ground.
McCown completed 20 of 30 passes for 303 yards and three touchdowns without an interception, providing a steady presence in a game that frequently threatened to become chaotic.
The Roadrunners didn't have to rely on him alone.
Henderson rushed for a team-high 89 yards, High added 76 and Peterson finished with 60 yards and two touchdowns on just six carries. Six different UTSA players reached the end zone.
Anderson was responsible for two of the game's biggest scores — his 100-yard kickoff return in the third quarter and the fourth-quarter touchdown catch that helped keep Colorado State at arm's length.
It was the kind of response UTSA needed after its offense struggled mightily against Texas.
The Roadrunners were held to 142 total yards and six points in Austin. Seven days later, they nearly quadrupled the scoring output before halftime alone.
There were still warning signs.
UTSA surrendered 500 yards, gave up 45 points and never completely put away a Colorado State team that continued finding ways back into the game. The Roadrunners' early special-teams breakdown also put them in an immediate hole.
But when Colorado State landed the first two punches, UTSA didn't fold.
When the Rams threatened again in the second half, the Roadrunners kept answering.
And after leaving Austin with plenty of questions about its offense, UTSA walked out of the Alamodome having provided a very different answer.
The Roadrunners are 3-1.
Now, conference play awaits.
